For the science fair I chose to see which of three liquid substances conducts the most heat. I learned that water conducted the most heat out of water, apple juice, and orange juice. I was interested in this project because I wanted to know why substances conduct more heat than others. This could be useful in emergency situations or for doing a science experiment. If something was to catch fire, it’s good to know how to extinguish it. Also, in conducting an experiment to find the flammability of an object, it’s good to know what materials conduct more heat to find certain reactions. Here is an example of my work:
5 facts about the sun: Made of gases called plasmas. The sun has an inner core that is dense and is about 15 billion degrees Celsius. Reactions inside the core make heat which is part of what provides light and heat for Earth. Without energy from the sun, earth would be a cold lifeless rock. No solid surface.
2 ways the moon moves: Rotates and revolves.
Explanation of night and day: Day happens when earth rotates towards the sun. Night happens when earth turns away from the sun. The number of hours of daylight depends on earth’s angle towards the sun.
Causes of the seasons: Earth revolves around sun. Sometimes earth is closer to the sun. This and earth’s tilt affect the change in seasons.
Solar eclipse: An alignment of the sun, moon, and Earth that blocks the sun from earth’s view.
Galaxy: A huge grouping of stars.
Describe Milky Way: Spiral galaxy. At least 100 billion stars.
Parts of asteroids and comets: Comets have small icy bodies, and asteroids have bodies of rocks and metal.
How planets differ: mass, and time for one revolution.
Light year: distance light can travel in a year. Is used because objects in space are so far apart.
Midsized star: nebula -> Midsized star -> Red giant -> white dwarf -> nova -> black dwarf.
Constellation: Part of the sky containing a certain group of stars. The Greeks gave them names according to their myths and gods. They appear to move because earth moves.
